Latest Message<\/th>\nTitle: Some users may see unwanted add-ins appearing automatically across all Outlook clients <\/p>\n

User impact: Users may see unwanted add-ins appearing automatically across all Outlook clients. <\/p>\n

More info: These add-ins are configured to be available to users by admins but aren\u2019t expected to be automatically installed. <\/p>\n

Current status: We\u2019ve developed and begun deploying the fix to the affected environments. We\u2019re monitoring its progress to ensure it propagates successfully, and based on our current estimates, we expect deployment to complete by Wednesday, August 26, 2026. We\u2019ll provide further resolution updates as they become available. <\/p>\n

Scope of impact: Impact may occur for some users that may see unwanted add-ins appearing automatically across all Outlook clients. This section may be updated as the investigation progresses. <\/p>\n

Start time: Friday, July 17, 2026, at 10:26 AM UTC <\/p>\n

Root cause: A portion of the Exchange Online add-in sync pipeline isn’t processing add-in state information as expected. This is causing incorrect EnabledStatus values being returned and Outlook automatically displaying add-ins configured as Available, which is resulting in impact. <\/p>\n
